Fe K edge XAS transmission of bulk LEOVILLE CV chondrite: raw spectrum

Comments

3 spectra were measured at different locations and averaged + the raw spectra were normalized using two polynomial curves, for the pre-edge region (linear curve) and the post-edge region (polynomial order: 2) while the edge jump was scaled by a factor to give a jump of 1. These normalizations were performed with the software ATHENA from the IFEFFIT package (Ravel and Newville 2005).

Comments

The resolution in the above table is the resolution given by the monochromator. The energy was calibrated by measuring the absorption edge of a reference: Fe metallic foil (first maximum of the derivative set at 7112 eV). The resolution of the spectrometer analyser was 0,365 eV (FWHM of the elastic peak).
